Urogomphi is correct. Those are rear appendages seen in many beetle larvae.
I suggest their use here is one of deception where the rear is a false head. When alarmed, perhaps it draws attention to the rear end and away from the more important head. Lots of insects use false heads of one kind or another.

I must be missing something here. The tentative ID was something like Schizotus, whose larvae bore in wood. Just intuitively, it doesn't seem to me that deception would play a very important role for a critter that lives in wood tunnels.

Am I imagining this wrong, or do you think the subject is something different?
